Euroscepticism is on the rise across Europe, new research has suggested, with little more than two weeks to go before Britons decide whether to remain within the EU.
Nonetheless, the Pew Research Center report found that a slim majority - a median of 51% - of respondents across 10 EU countries still favoured the EU.
Forty-two percent want more power returned to their national capitals.
Another poll has found most Europeans want the UK to stay in the EU.
The findings, by TNS (in French), contrasted with its survey among Britons, which found that 41% supported remaining within the 28-member bloc, compared with 43% in favour of leaving.
The UK holds a referendum on 23 June on whether it should stay in the EU or leave.
In its poll results released on Tuesday, the Pew Research Center found a majority of people were unfavourable towards the EU in Greece (71%) and France (61%).
That followed a steep decline in EU favourability in France (down 17 percentage points from 2015 to 2016) and Spain (down 16 points over the same period). In the UK, support was down eight points, and in Italy six.
In five of the six nations surveyed in both 2015 and 2016, it found favourability had declined.

This year, the poll surveyed 10,491 respondents in 10 EU nations from 4 April to 12 May - nations accounting for 80% of the EU's population and 82% of its GDP.
It found the strongest supporters of the EU were in Poland (72%) and Hungary (61%) - compared with just 27% of Greeks, 38% of French and 47% of Spanish.
In Monday's TNS poll, Germany was the country where the greatest number of respondents felt the UK should remain within the EU - 79%, compared with 15% who felt it should leave.
